应用PH3管道发生器地槽熏蒸杀虫，较常规熏蒸有三个方面的突破：一是改PH3气体由上向下渗透为由下向上渗透、扩散，基本避免了毒气泄漏，有利于毒气在粮堆中的均衡分布并达到有效致死浓度；二是改熏蒸探管垂直没药为管道发生器横向施药，管道长度和扩散面积大大提高，加速了毒
PH3 pipeline generator fouling insecticide, fumigation than the conventional three breakthroughs: First, change the PH3 gas from the bottom up through the infiltration from the bottom up, proliferation, basically to avoid the gas leak, is conducive to the gas in the piles In the balanced distribution and achieve effective lethal concentration; the second is to change the fumigation probe vertical myrrh for the horizontal generator of the pipeline generator, the pipe length and diffusion area increased greatly accelerated the toxicity
